The mount.sh handler attempts to prevent already-mounted filesystems
from being mounted as dynamic/removable "/media". But it misses the
case where the kernel has mounted the root filesystem (e.g. with
"root=/dev/sda1"). In that situation, /proc/mounts has a device name
of "/dev/root" instead of the proper $DEVNAME string exposed by udev.
So we must also test the root filesystem device number vs. the
$MAJOR/$MINOR udev tells us.
